BRUSH-BRIDLE.

Application filed November 30, 1914. Serial no. 874,837.

To all whom it may concern Be it known that T, GILBERT 0. Burns, acitizen of the United States, residing at VVorcest'er, in the county ofWorcester and State of Massachusetts, have invented a new and usefulBrush-Bridle, of which the following is a specification.

This invention relates to a bridle for a brush and although capable ofgeneral use is particularly adapted for a stiff bristled brush having arelatively large area over which the bristles are distributed, andespecially for brushes having metal bristles.

The principal objects of the invention are to provide a bridle entirelysurrounding the body of bristles and especially to provide aconstruction in which the bridle can be formed of two wires secured tothe body of the brush at the ends thereof instead of at the sides, andto provide a simple, convenient and inexpensive means for securelyholding them in position at the ends of the brush.

Reference is to be had to the accompanying drawings in which Figure 1 isa side elevation of a brush constructed in accordance with thisinvention; Fig. 2 is an end elevation thereof Fig. 3 is a sectional viewon the line of Fig. 2; and Fig. 4.- is a bottom plan.

The invention is shown as applied to a brush for use in cleaningmeat-blocks. This brush comprises a solid back 10 and a plurality ofrows of flat wire bristles 11. Ordinarily in the manufacture of brushesof this and similar kinds, the bristles are arranged.

as near as possible to the sides of the brushback so that there is noconvenient place in which to secure a bridle, and for this reason I haveprovided for-securing it at the ends but it is to be remembered that theend bristles are the ones which are most fully protected by the bridle,and consequently the bridle should extend along all the end bristles andhave its full strength and efiiciency clear across the end of the brush.

The bridle preferably is made mainly of wire. Two wires 13 are shownalike in all respects, each having a horizontal main part, a transversemember or arm 14 at both ends and a vertical sharpened end or leg 15transverse thereto adapted to be driven into the body of the brush justat the ends thereof. These horizontal bends 14 of the two wires are inthe same place at each end and also in Patented Sept.

direct alinement with each other. i F or the purpose of securing themtogether, although they are located at a distance apart, astrip' ofsheet metal 16 is provided having two notches 17 along of the longedges. The unnotched long edge is bent inwardly over the two horizontalmembers 141 until it engages the inner surfaces of the vertical ends 15.The opposite notched edge is bent downwardly around these members 14Land comes into contact with the unnotched edge mentioned. The twonotches are spaced just farenough apart to receive the tops of thefastening ends 15. *When this is secured.

force the wire members to the same positions on all the brushes, and ateachend of each brush, so as to insure that all the bridles shall beuniform in shape and size. In this way the bridle is caused to surroundthe entire body of bristles and present a strong, smooth surface at theends, a d furthermore the joint'between the two edges" of the member 16is entirely hidden by being located on the inner side neXt the bristles,and it is firmly and securely fixed without the necessity of employingskilled workmen to place it properly in position.

Another feature of importance lies in the fact that the cylindricalmember 16 is larger in diameter than the wire of which the rest of thebridle is made. Consequently the end bristles engage a wider surface andthere is little danger of their being bent over at an acute angle. Thistends to keep them straighter than in those cases in which only a smallwire is used to resist the bending of the bristles.

. Although I have illustrated and described only a single form of theinvention and shown it as applied only to a single style of brush, I amaware of the fact that many modifications can be made therein by anyperson skilled in the art, and that it can be applied to other types ofbrushes without departing from the scope of the invention as expressedin the claims. Therefore, I do not wish to be limited to all the detailsof construction herein shown and described,

nor to the particular kind of brush illustrated, but Q What I do claimis 2-"- 1. As an article of manufacture, a brush bridle comprising twowire members each having a main body portion adapted to extend along thebody ofbristles of the brush at the side thereof, and arms bent inwardlyat both'ends in the sameplane, and means in the plane of said arms forfastening the I said arms together.

52; As an, article of manufacture, a brush bridle comprising two wiremembers each havin a main body portion adapted to extend along the bodyof bristles of the brush at the sidethereof, and arms bent inwardlyback-for fastening the said arms together.

I 3. As an article of manufacture, a brush bridle having a air of, legsspaced apart at .each end of the 'ody of bristles, secured in the'brushback, and extending I normally j from the plane. thereof, said legsbeing bent outwardly in oppo'site directions at their extreme ends toform arms in alinement with each other and then being bent again atright angles in the plane of said arms to form main body portionsparallel to each other, '.anda tubular member surrounding said arms andconnecting said legs together. 4. As an article of manufacture, a brushbridle comprising two wire members each having arms bent inwardly, theends of said arms being bent at right angles to form legs to permit offastening the same to the brush back, and means for fastening the saidarms together, said means consisting of a hollow sheet metal membersurrounding said arms separated along one side and having apertures atthe edges for receiving the tops of said legs.

5. As an article of manufacture, a brush bridle having a hollowcylindrical sheet metal member at the end for engaging the bristles andholding the parts of the bridle in position, said member throughout partof its length substantially surroundinga part of the bridle.

6. As an article of manufacture, a brush bridle comprising two wiremembers each having a main body portion adapted to extend along the bodyof bristles of the brush at the side thereof, and arms bent inwardly atboth ends in the same plane, the ends of said arms being bent at rightangles to that plane to form legs to permit of fastening the same tothe. brush back, and means at both extremities for fastening the saidarms together, said means consisting of a hollow sheet metal tubesurrounding said arms and having apertures for receiving the tops ofsaid legs.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing witnesses.
